Product Description

The PROOF RESEARCH PXT Carbon Fiber Barrel Blank in .308 Winchester combines next-generation rifling technology with the legendary lightweight performance and precision PROOF Research is known for. PXT -- PROOF Exponential Twist -- is a complete rethinking of conventional rifling geometry and twist progression, engineered to reduce engraving force, minimize throat erosion, and create a smoother transition as the projectile engages the rifling. By dramatically reducing the rifling lead angle and smoothing projectile engagement into the bore, PXT technology helps reduce wear, improve shot-to-shot consistency, and create less felt torque during firing for improved recoil control and the ability to stay on target more effectively. Built on PROOF's proven carbon fiber construction, this barrel blank delivers an exceptional stiffness-to-weight ratio and reduced overall rifle weight without sacrificing accuracy or durability. Designed for custom rifle builders and gunsmiths, this blank offers a premium foundation for lightweight hunting rifles, precision long-range systems, and modern high-performance rifle builds.

Product Highlights

  • PXT Rifling Technology: PROOF Exponential Twist reduces engraving force and minimizes throat erosion for a smoother, more consistent projectile engagement.
  • Extended Barrel Life: Controlled testing has demonstrated a 30-100% increase in barrel life compared to conventional rifling, while maintaining PROOF's exacting accuracy standards.
  • Carbon Fiber Construction: Provides an exceptional stiffness-to-weight ratio, reducing overall rifle weight without compromising rigidity or performance.
  • Sendero Contour: Features a Sendero contour with a 1.20" shank diameter and 2.5" barrel breech, making it ideal for precision long-range and hunting rifle builds.
  • Custom Builder Ready: At 20" in length with a 1:10 PXT twist rate, this blank is purpose-built for gunsmiths and custom rifle builders seeking a premium .308 Win barrel solution.
